To create the HUD, he’s using a semi-transparent mirror which he took out of a game of Khet 2.0 called the Eye of Horus Beamsplitter — which is a really cool real-life puzzle board game like those games where you have to reflect the laser to solve a puzzle. He’s then using a 3x Fresnel magnification lens which is placed over top of his 2.4″ LCD in a 3D printed enclosure. This magnifies and reflects the image onto the mirror which is placed directly over his eye, allowing for a see through display.

Stick around after the break to see a video of the Raspberry Eye in action!

I don’t think we need to call every HMD a “DIY Google Glass”. This kind of tilted combiner is old. It’s not seem much commercially because it’s bulky as hell at larger sizes. Just call it a head-mounted display because that’s what it is.

Needs a Camera fed to an OCR data-logging the recognised text while a second camera monitors what you stare at and a Heart beat logger and blood pressure monitor EMF meter + a Gyro meter and a Infrafed spotlight.. and object recognition with a GPS receiver.

exactly!! if that kind of “lens” or “mirror” or “combiner” or whatever it is capable of producing the image representation somehow “further” from our eyes, then it will be perfect! Does google glass have this focusing problem?

Why mount everything on the head? Most of that could go in a container and clip onto your belt and then have the wires running up to the unit (perhaps inside a cable tidy so it acts like a single cable).

I’d like to point out that he made it, you didn’t. He has the skills, and you don’t. You don’t have a whole lot of room to criticize. I don’t think his intention was to make a stylish piece of technology to market to the masses. He was doing what any hacker would – experimenting. I guarantee you Google Glass looked a whole lot like that at one point in its development cycle.

Is the eye of whatever part custom made for the game, as linked, out of a cd case, or is some other special material required? The fresnel is not a common item so I’d not be suprised if the lens was special too.

It is 140g without the head strap. I did not try to wear for long periods yet, the wireless keyboard I have is not really good for normal use. If you need to see the screen only occasionally then some kind of flip-mount would be useful, but this would require using precision metal parts. Constant use for long periods may be unsafe for the vision.
